>> Hey everyone, quick question, more an idle thought. When exim looks up a mail to be delivered via remote_smtp, it seems to always prefer to use IPv4 even when a v6 address is available. For example, in my log I see a message delivered to a gmail address. But both Source and Destination IPs are ipv4 format, even though dig aaaa gmail-smtp-in.l.google.com shows a ipv6 address. Is there some option somewhere that can be set that will tell exim to deliver to IPv6 addresses unless no such address is available, and then fall back to IPv4?

Maybe disable_ipv6=true
in your config. Or daemon not listening on the v6 address ?
